Well they pulled all the aux drive stuff, rebuilt the blower, got a mechanical oil pressure gauge and new filters on my 8V92 and we are planning on starting her Friday morning!

For those of the praying persuasion prayers would be appreciated. For all other keep your fingers crossed.

If Gumpy doesn't have to work maybe I can talk him into coming out with me. I'll try to bring a camera and record the moment.

he said the blower vanes looked new but the seals were brittle and in need of replacement he also mentioned that the governor still had a locking tab on the high idle adjustment which led him to believe the motor has been rebuilt. I have no idea what he's talking about but I betcha Clifford does.

Unfortunately, I'm probably going to have to work that day, and probably in Burnsville.

I'm in the middle of a formal qual test and it's kind of a one man show at work right now. The good news is they've authorized some OT for me for a couple weeks. The bad news is they haven't told me if they're going to extend my contractat the end of the month.

Well, it certainly didn't go as well as planned. It had a nagging blue smoke issue that wouldn't go away even at full throttle. I am kind of at a crossroads with this motor. I mean, how far do you go?? Because it started right up and had great oil pressure (almost 60 lbs at full throttle) I'm sure that a local trucking guy would throw it in his truck in an instant but he's always relatively close to home, we on the other hand, have a 2500 mile trip planned to Yellowstone this summer. The $2K question is do I want to change out the injectors, do a full tune up and fix the turbo and see if it clears up (to the tune of 2K) or do I want to cut my losses on this thing. It's also leaking ouf the airbox drains (that could be old oil that's in the drains because it sure looks black and we have new oil in the motor) and that didn't put my mind at ease either. I videotaped it and I'm going to try and figure out how to upload them later so I can get input from you all.

With all the stuff that I am going to have to find/buy for the changeover I am losing confidence in the repower.

Bet you a steak dinner Rick you put that engine on a dyno under a load for 2 hours and that puppy will clean up. Van's 6v92 looked like it was junk till he drove it 200 miles it poured a quart out of the drains in 20 miles and smoked like crazy now it is clean, he was really bumed out at start up.

Do what Clifford said, Rick. Run it into the ground, if you don't want to dyno it. Take the next weekend or two, and just drive. Anywhere. See if it fixes itself. Just might save you some $$$. But then again, 2k for a rebuild doesn't sound bad. Why? Because if we did that it would be a whole lot more...lol.

John, I'm sorry but I have failed to make clear is the motor is on a stand not actually in the bus yet and it is going to need alo of retrofitting to do the switchout. Starter, water pump,oil pan, bellhousing, flex plate, cradle, front motor mount, custon intake and exhaust, muffler so even if it was perfect I would have alot in parts for the retrofit. I would do the labor but these parts are expensive and hard to find to say the least.The 2k is just to replace the compressor wheel and seals on the turbo, and to run a compression check on all the cylinders and give it a new set if injectors and a serious tune up, Curt said the rack was way out of whack and that the valve timing is probably way out as well. I will try and upload the video so everyone can see what I'm talking about. Leave it to Clifford to make me start believing again!

The truth is I have an excellent running 8V71 and I think after the cooling system rebuild she can clear the Rockies so I don't have a whole lot to lose either way right now. But you start getting 10k into a motor and you are out of my tax bracket.

Anybody got any quick hints on uploading video?? Is it the same as photobucket?

Rick, Glad it started. I can't tell you much from the video, but my 692 would have smoked you out of that shop LOL! The smoke is gone now and mine was blowing oil from both tubes, I got 400 miles with mine now,the blowing oil is now just a few drips after shut down, and it keeps making more power too! But I didn't have much of a choice cause the old engine was toast and had to be replaced. Your motor did sound strong,and the smoke... Don Fairchild told me see if it'll clean up, drive the heck out of it, but don't break it. The engine starting up rite away is a good sign, means it has good compression. Did you guys run the rack yet? I know the position you are in, all the best.V

Sure looks like you ran the 8V-92TA without water hooked up to it. It doesn't take alot of running to burn up the cylinder O rings. At this point, it would be prudent to take the engine apart to see what is worn and bad with it and reassemble with new replacement parts, instead of installing an unknown. After running the engine like you did without water, I sure wouldn't install it in my bus without a full tear down and reassemble. Good Luck, TomC

Hey all,The motor was completely full of water and we had all the air out of it. I should have mentioned that earlier.Tom, I honestly can't afford to tear into this motor like that, if there wasn't a single worn out part on it the bill could be 5-6k in labor just to check. I wish I could but I just can't justify that with two young kids and a great running 8v71 already in my bus. I remember reading how much your power upgrade cost and thinking I wish I could afford that. I'm calling around in the morning to see how much a couple hours on the dyno will run.I have taken a breath, and have decided it may be worth it to run it after hearing Van's story. I know you all know how valuable this blog is when you're struggling.Thanks for being there. I am grateful.Rick

Do what Clifford tells you is my advice. Has to be the cheapest way to go. The dyno will tell you if you need to do a compression test and if the injectors are shot and even if the rack needs run immediately. Clifford will just love his steak dinner...bet'cha. Keep him on the phone while the dyno run is in progress.

The very best of luck Buddy,

John

Rick, I would have to agree with Clifford. But this is not a sure thing, same as your 8 71 making it out west and back. I had an injection pump rebuilt, the guy told me when I picked it up there was now a knock in it. Probally an injector leaking, I started home and turned around. It sounded like she was going to come apart. He put some injector cleaner in the tank and in 5 minutes the sound was gone. Never had another problem. Moral of the story trust the experts, not people like me. There are a few on here and some have had real experiences with these. I still think it will clear up. Tom Y
